Paper-dispensing machine



a proper number of intake valves and exhaust valves (not shown) areprovided. Instead, however, of operating said valves by means of pushrods and rocker arms, said valves are operated in the desired timedrelation by overhead camshafts 25 and 26. These cam shafts,.two for eachcylinder group, are disposed in parallelism and have an over-all lengthsuflicient to span the total number of cylinders comprised in eachcylinder group. In Fig. 3 it will be noted that the cam shafts 25 and 26are mounted in suitable bearings 27 fastened to cylinder head coverplates 28 which are in turn fastened to the cylinder heads. Said coverplates 28 are preferably of one piece construction and are adapted tobridge the space between the cylinders of the respective groups and atthe forward end of said groups are adapted to overhang the group seriesto provide housings 29 within which suitable gearing 30 for the camshafts is enclosed. Cover plates thus characterized reinforce thecylinders of each cylinder group and at the same time providean-adequate at: tachment surface to which the cam shaft housings 31 arefastened. A valve gear of the character herein disclosed is essential.At speeds exceeding 2000 RP. M. push rods and rocker arms, due toinertia forces, are incapable of continued operation for periods of longduration.

The means for driving the cam shafts 25 and 26 (in addition to thegearing 30) comprises a plurality of radially arranged drive shafts 32which, at their outer ends, enter the cover plate overhangs. Said shafts32 at their inner ends are carried into the crank case 10, each shafthaving mounted on said inner end a bevel gear 33 which meshes with asimilar gear 34 mounted on the engine crank shaft. Each said drive shaftis operated at the desired speed of rotation, due to its gearedconnection with the crank shaft,

and in its relation to the cylinder group which it serves, extendsradially out from the crank shaft in line with the radial plane of itsassociated cylinder group.

As is customary in aeronautical internal combustion engines, a certainnumber of engine accessories are essential to the proper operation ofthe engine herein described. Such accessories include a carburetor 35, afuel pump 36, an oil pump assembly 37, two distributors 3838, a magneto39, an engine starter 40, and a generator 41. Preferably suchaccessories are grouped radially aboutan extension .42 of the crank case10 so that any or all of such accessories may be removed or replacedwith as little inconvenience as possible. The crank case extension 42 isfastened to and against a rear end blower or compressor 43, the latter,as indicated in Fig. 4,. being directly fastened to the rear end of thecrank case. directly driven off the crank shaft 12, is so Said blower43, which isv formed and constructed as to providewithin the crank caseextension 42 a fuel induction passage 44. This passage 44is open at oneend to the carburetor 35 and at its opposite end widens outwardly toform the casing within which the blower 43 is enclosed. From said blowercasing the fuel mixture is fed radially to the cylinder intake ports 22thru the intake manifolds 24'.

In addition to driving the blower 43, the crank shaft 12, thru its rearend driving terminal 14,- is directly geared as at 45 to a counter-shaft46." This counter-shaft 46 has an axis of rotation parallel with theaxis of rotation of the crank shaft tho it is enclosed ter-shaft 46 anddirectly driven off the worm ear 47 there is provided a vertical shaft49.

k aid vertical shafts 49, which extend parallel, are journaled at theiropposite ends in bearings 50, and at one end are extended beyond theunderside of the crank case extension wall. One of said shafts hasmounted at its extended end the fuel pump 36,whereas the other of saidshafts is still further extended to drive the oil pump assembly 37 saidpumps 36 and 37 like the carburetor 35, being fastened exteriorly of thecrank case extension on the underside of its bottom wall. As illustratedin Fig. 5, the shafts 49 are located one each at opposite sides of thefuel induction passage 44. Transversely extendingstub shafts 51-51,geared as at 52, one each to each vertical shaft 49, extend laterallyout from the fuel induction passage 44 to drive the distributors 38which are mounted exteriorly of and against the opposite side walls ofthe crank case extension 42.

The magneto 39 and the engine starter 40 are also mounted exteriorly ofand against the opposite side walls of said crank case extension. Thedriving connection for said accessories 39 and 40 consists of atransverse shaft 53 having a bevel gear. 54 mounted thereon and meshingwith the bevel. gear 48 mounted on the end of the shaft. Saidaccessories 39 and 40, however, are disposedin a horizontal plane abovethe corresponding plane of the shafts 51 and in a transverse verticalplane longitudinally removed from the transverse vertical plane of thevertical shafts 49. Moreover, if desired, by the provision of a verticalstub shaft and bevel gear (not shown) the generator 41 may be likewisedriven olf the bevel gear 48. Preferably said generator 41 is mounted onthe exterior top side of the crank case extension 42.

-This invention relates to improvements in dispensing apparatus andhasparticular refere-nee to a machine of the type wherein a continuous webof paper is 'fed to 'a cutter to be severed thereby into predeterminedlengths. l

An object of-the invention is to provide an improved machine ofpractical construction in which a continuous web of-paper is fed to'acutter which .is operated, by the means which feeds the paperthereto,-'to sever said web into predetermined lengths.

Another object is to provide the machine with two web-feeding devices sothat difierent predetermined lengths ofpaper may be fed to a cutter,either of said devices being effective to control the operation of saidcutter. The above and otherobjects will appear more clearly from thefollowing detailed de scription, when taken'in connection with theaccompanying drawings, which illustrate a preferred embodiment/of, theinventive-idea.-

' Thepresent machine is especially designed for dispensing parchmentpaper or the like,

' such as used in stores for providing inner wrappers for foodproducts,but it is to be expressly understood that the machine is not limited tosuch use, the scopeof the invention being defined by the appended claims"The machine comprises a casing'10 having a removable cover l1 and frontand rear walls 12 and"13., Mounted upon the side walls 14adjacenttherear of; the casing are 7 opposed brackets .15 vertically slotted, as indicated in, dotted lines in Figure 2, to re ceive the ends of afree-floating shaft 16j which carries-the continuous web of paper ,17-infthe form of a-rollwhich rests'ujpon th'ebottom of-the casing at alltimes as'the 1 diameter of 'the'roll decreases. The web-of paper'is'fed'on to a guide in the nature of a platform 18'supported-within thecasing. longitudinallythereof and having its i'e'ar, end disposeddirectly above the roll of pa er: The platform '18 extends to a pointadjacent the front Wall 12 of the casing which is provide'd with an"outlet 19 through whi'chj'sev cred sheets are withdrawn'from thecasing,

and the forward portion 20 of said-platform: is inclined downwardly forpurpose which will appear'in the-course of the description. In order toproperly guidethewebof paper,

- the longitudinal edges of the platform are doubled upon themselves topr0vide overhanging fianges21 whichforni channels for 78receivingthelongitudinal edges of-saidjweb; Substantially coextensivewiththe platform 18 andalong the longitudinal edges thereof there aresupported tracks 22 and 28, the entire lengthof each of which is-inthesame plane so that the forward end of the track" will be elevatedabove the inclined portion 20 'ofthe platform. Y 7

In the track 22 there is mounted fol-slid; ingmovement longitudinallythereof a feeder generally indicated by the numeral24, while in thetrack 23' a similarly constructed feeder 25 is mounted-for'slidingmovement. 7 Thesei feeders are alternatively used for f feedingdifferent lengths ofthe web 17 along'the 90 platform '21 to a cutter tobe later described and, "for'this purposeysaid feeders-are dis posed innormal positions at difi'erentj disk tances from the forward" end ofsaid platform,so=that the movement of either feeder along its track to apoint-contiguous to. the" rear end of the inclination 20 of the platformwill advance a different length of the web; 17 to the cutter thanthatwhich is advanced by the other feeder. i I

. determined length of the web.

,Each feeder comprises a shoe 26 slidable I in its track and having an.operating lever 27 pivotally connected thereto and projecting through alongitudinal slot 28 formed in the.

cover 11 with its outer end adapted to be grasped in a hand oft-he'operator when it is desired to obtain a severed sheet from'themachine. Extending inwardly from the lever 27 of each feeder andoverhanging the platform 18, is an arm 29,the inner end of which hassecured thereto a gripper member '30 of rubber or any othersuitable material which, in the normal position ofthe lever 27, is slightly raisedabove theweb v17, but. which'is adapted to engage said web when thelever: is thrown rearwardly about its pivot, which is the initialoperation'preparatory to advancing the w-eb toward the cutter.

'Wherithe lever is thus operated, a-coil spring 31 connecting the samewith its shoe 26. is compressedso that, upon release of the lever by theoperator at the conclusion of theop; f eratiQH', said lever is restoredto. its normal, position and the gripper again disengaged from the web.In its normal jposition the feeder is prevented from rearward movementalongits track by a stop member; 32 in .the form of a wire or small rodhaving its ends bent for insertion into any one of a seriesof opposedpairs of openings 33 in thetrack of the feeder; This stop member isadjustable to any positionalong the track so as to vary the normalposition of the feeder, whereby thesamemay be caused to advance any.pre-

Means are provided in; connection with each feeder for restoring thesame toits nor-.,

mal position against its stop me'mber32, followlng ts forward movementalong the track thereof and the release of the lever 27 by the operator.This means comprises a flex-s ible band or tape 34, one end offwhich isconected to the shoe 26 of its respective feeder-, sa d band extendingrearwardly from said shoe and over an idler 35 at therear end;

of the feeder track. From this idler the band extends, to admin 36mountedupon the base of'the casing 10 and upon which said band' iswound. A spring 37 is ,coiled within'the drum and its outer extremityconnected thereto, while the inner end there of issecured upon a shaft38 projecting from said drum. 1 This shaft has associated there:

with an escapement mechanism includingthe '3 ratchet39 and pawl 40 whichceoperate to holdthe shaft and maintain the spring 37 7 under; tension.By turningtheje'nd of the,

projecting shaft 38? in a clockwise direction, as: viewed in Figure 2,theftfcnsion 'of the ,1 spring 37 maybe increased and, by tripping the,pawl 40 to. permit of stepf-by-steprota-v V tion of the shaft 38, in anopposite. direction,

said tension may be decreased. 'It. will thus be; seenthat, when one ofthe feeders is pulled 6.5 forwardly by the operatoraf te'r thelever 275of the feeder has been swung rearwardly to engage the gripper member30with the web of paper,the latter will be advanced and at the same timethe band 34 will be unwound 1 from the drum. 36, thereby putting thespring 37 under the tension necessary to automatically return the feederto its-normal position when the lever 27 has been released. 7

As either feeder is drawn forward, during which the lever 27 thereofheld the operator in its rearward position, the gripper member 30continues to engage theweb 17 until the" rear end of the inclinedportion 20. of the platform reached. Then, as the guide flanges 21 andat the point of emer gence of the web therefrom a, stationary cutter bar41, to one end of which. there is pivk 'oted, as at '42, the movablecutter 43 which,"

in its normal position, is raised above the platform and; yieldably heldin such position by 'a retract-ileispring 44, one end'of which isconnected to the free end, of said cutter and the other end of saidspringis joined to the upper end of a standard 45secured to I p the baseofthe casing (Figures 3. and 5-). Alsoconnected to the free. end of the.cutter 43 is one end of a -link 46, .the other endof which is joined toalever 47. pivoted, i i-ten mediate its ends as at 48;, toa standard: 49also supported upon thebase, o-fthe casing 10. The other end of thelever 47 engages a. tripi50 in the form, ofa. bell-crank, pivoted tosaid standard 49 andhavingonezend; pro.- jectinginto. the. track 23.0.fthe feeder 2' 5Qso as to be contacted'by the shoe '26; of saidfeederflas the latter approaches the-endfof its forward movement, said:Inovement being; limited by a stop member. 51 similar to the, members32', Upon contact-of the shoe 26 with the trip '50v the latter is.rocked abou its.

pivot and,.' inso doing, imparts a similar movement to vthe.lever4-7,throwingthe front end thereof downwardly pulling "the; cutter43 therewith. sogthatthe latter will-1cooperate with the cutterbar 41tosever the desired n th Of rare r m. t e We the major portion of whichlengthis at; this timeprojected through the opening 1 9 and.

can fol lowin-g its severance. from the; W.ebV-,' be thdr wn r m smeshmerd to. producea shearing action between the bar 41 and cutter, 43;, thelatteigin its no mal posi;

tion, ext ndsze igh -aneler la ire be? the vertical plane of the bar 41so as to partially overhang said bar, as best indicated in Figure 1. Thecutter is yieldably maintained in this position by a leaf-spring'52, thelower end of which is secured to the standard 45 while the upper portionof the spring engages the free end of the cutter 48 and forces the samerearwardlyso as to position it diagonally, as previously mentioned. Theten sion of the spring 52, and consequentlythe amount of its lateralpressure against the bar 41 as thecutter is operated, may be regulatedby a set-screw 53 mounted on the standard 45'and engaged with saidspring. Upon. release of the lever 27 from its position in' Figure thesame is thrownforwardly by its spring 31 and simultaneously the'spring 137 of the winding drum, which is at this time under tension, operates towind the band 3 L upon said drum and thus pull the feeder 26 rearwardlyuntil it contacts its associated stop member 32. At the same time thespring 44 of the cutter 4E3 acts to restore the to its normal position.The operation of severing a latter the opposite side of the platform18:.from the feeder wilf now be described The web 17 is advanced in-thesame manner as previously described to the cutting pomt,

whereupon the continued advancement of the feeder 24 causes its shoe 26to contact the end of the bell-'crank'lever 54: which prov jects intothe track 22. Said lever- 54 is similar to the trip and is pivotallymounted upon the standard 55, with its other end in engagement with therocking lever 56 cor-l responding to the lever 47. The forward end ofthe lever 56 is connected by a link 57 to the free end of acutter-actuating arm 58, the othere'nd of which is pivotally con nectedto the'standard 45. Intermediate the ends of this arm a pin59projectstherefrom and rests upon the upper edge of thescutter Withthis construction, when the shoe 26 of the feeder 24 rocks thebell-crank lever 54 about its pivot, the lever 56 is operated to pulldown upon the link 57 and thereby cause the arm 58 to eXert'a downwardpressure upon the cutter which then cooperates with the bar 41 to severthe web. Release of the lever 27 of the feeder 24 then permits thelatter to be restored to its normal position in the same manner asdescribed in connection a. with the feeder 25. w
